UNITED STATES PATENT OFFICE.

BENJAMIN HEWITT, OF BIRMINGHAM, ENGLAND.

PLUMBER-BLOCK.

SPECIFICATION forming part of Letters Patent No. 226,747, dated April 20, 1880.

Application filed March 16, 155804 (No model.) Patented in England February 18, 1879.

To all whom tt may concern:

Be it known that I, BENJAMIN HEwIT'r, residing at Birmingham, England, have invented new and useful Im provementsin Plumber-Blocks and other Bearings, for which I have obtained a patent in Great Britain, No. 655, dated the 18th day of February, 1879, and of which the following is a specilication, reference being had to the accompanying drawings, making part of this specitication.

This invention, which relates to certain improvements in plumber-blocks and other bearings for machinery, has especial reference to improved means of adjusting the brasses77 or bearing-collars by which the shafting is supported in the block, so as to keep the saine at all times true and parallel with the shafting, and to obtain a proper bed or seating for the shat'ting to revolve in without disturbing or packing the block itself, and so as` to be able to raise or lower the bearings as the shafting may require through wear or other causes, and to facilitate the litting of shaftin g to run truly both vertically and horizontally.

Thisinvention consists in constructing plum ber-blocks with upper and lower inclined surfaces, against which bear wedge-shaped adjusting-pieces, between which the brasses or bea-rin gs for supporting the shafting are placed, said plumber-blocks being provided with an opening at their upper part, to admit of the shaftin g being placed in position between the brasses or bearings.

In the drawings, Figure l is a side elevation of a plumber-block. Fig. 2 is a transverse section of the same. Fig. 3 is adetached perspective view of one of the adj listing-pieces. Fig. 4 is a detached perspective view of one of the brasses or bearings. Fig. 5 is an end view of the plumber-block.

Referring to the drawings, the numeral l designates my improved plumber-block, having a suitable base with openings for the passage of bolts, whereby it -can be securely lined toa supporting-base. This plumber-block is formed with upper and lower inclined surfaces, 2, against which bear the wedge-shaped adjusting-pieces 3, between which the brasses or bearings 4t, for supporting the shafting, are placed.

The'top of the block lis made open at the part 5, as shown in Figs. 1 and 2, to admit of the shaftiug being placed in position between the brasses, and the inclines 2 are formed by hollowing out the block transversely ofthe direction in line of the shafting, as shown best in Fig. 2.

Each adjusting-piece 3 is made or fitted with a screw pin or extension, 6, and its position is shifted and determined as desired by means of a nut, 7, thereon. Upon turning the nuts the pieces 3 are caused to move toward or away from them, and thus to raise4 or lower the brasses or bearings, as may be required.-

Each piece is slightly hollowed out on its inner side, as shown in Fig. 3, and the brasses or bearings 4, (see Fig. 4,) against which the pieces 3 bear, are formed to a similar contour, as shown in Fig. 5, by which means they have such freedom of movement as will insure them keeping at all times true and parallel with the shat'ting, the latter at all times running truly, and being thus subjected to a minimum amount of friction.

The above-described improvements are applicable to all purposes in connection with machinery or other apparatus where similar adjustments are needed.

What I claim isl. A plumber-block or bearing for shafting, formed with an open top for the introduction of shafting, the brasses, or bearings, and with recesses having upper and lower inclined surfaces, 2 2, in combination with the wedgeshaped adjusting-pieces 3, having screw-extensions 6, substantially as described.

2. rllhe combination, in a pillow-block, of the movable brasses or bearings having rounded or curved backs with the adjusting-pieces 3, having screw-extensions G and concave inner faces coinciding with the contourof the back of the brasses or bearings, substantially as described.
